What I can say is that for carbon dioxide to be sequestered, I agree that if there is a large point source such as a coal plant, and if that coal plant is sitting over a formation or is close to an EOR or enhanced oil recovery facility, there is a significantly higher probability of getting the CO2 out of the flue gas and either sequestering it in the formation under the coal plant or moving it to an EOR facility. To the extent that we have a number of those kinds of coal facilities—particularly, if you look in Alberta, all of our coal plants that are up west of Edmonton sit over those geological formations and are close to enhanced oil recoveries—we have quite a high potential for sequestering CO2.
As to the point about the oil sands, I agree that CO2 sequestration could be more difficult, if the CO2 sources are more disparate. But certainly if you're looking at coal plants, and particularly if you're looking at the coal plants in Alberta, and particularly if you're looking at the project we presented, you have a very high probability of sequestering CO2.
